BACKGROUND

Mobile communication devices (e.g., wireless phones) have become an integral part of everyday life. For example, a user traditionally used a mobile communications device to place and receive telephone calls when the user was away from a fixed communications device, e.g., a house or office wired telephone. In some instances, the mobile communications device became the primary device via which the user communicated with other users as the user became accustomed to the convenience and functionality of the device.

Communication techniques that may be employed using a mobile communications device have also increased. For example, users were traditionally limited to telephone calls between mobile communications devices. Advances were then made to provide a variety of other communication techniques, e.g., text messaging and email. However, inclusion of these additional communication techniques on mobile communications devices having traditional form factors may cause these devices to become unwieldy and less suitable for mobile applications. For example, traditional input devices that were employed by these communication techniques may be less suitable when applied by traditional mobile communications devices.

SUMMARY

Alternative inputs of a mobile communications device are described. In an implementation, a mobile communications device includes a display device having touchscreen functionality, a keyboard having a plurality of physical keys that include a dedicated key and letter keys arranged according to a QWERTY layout, and one or more modules. The one or more modules are configured to output a user interface on the display device responsive to selection of the dedicated key, the user interface having a plurality of portions that are selectable via the touchscreen functionality to cause input of a respective one of a plurality of emoticons.

In an implementation, a determination is made that a physical letter key of a keyboard of a mobile communications device has been selected. If the physical letter key has not been selected for a specified amount of time, a letter is input that corresponds to the physical letter key. If the physical letter key has been selected for a specified amount of time, an alternative input is displayed that includes the letter on the mobile communications device, the display of the alternative input being selectable to cause input of the alternative input.

DETAILED DESCRIPTION Overview

Users continually desire increased functionality from mobile communications devices, e.g., gaming devices, wireless phones, mobile messaging devices, calendaring devices, and so on. For example, users may maintain a calendar, a list of contacts, send and receive text messages, access the Internet, send and receive email, take pictures, send status message (i.e., status update) of a social network, and so on. However, interaction with this increased functionality in conventional mobile communications devices may be difficult due to traditional form factors that were employed to keep the device “portable”, which traditionally resulted in small keys that were difficult to use and/or a large form factor that became less and less portable in order to provide sufficient space for each of the keys of a keyboard.

For example, “QWERTY” keypads on a mobile communications device have a limited amount of space for each of the keys on a standard keyboard, such as keyboard used in a desktop environment to enter Latin characters. As a result, the size of keys and/or the amount of keys included on the device are limited and are typically balanced, e.g., a number of keys and a desired size of the keys.

Consequently traditional manufacturers of QWERTY mobile communications devices (e.g., wireless phones) may load secondary and tertiary functions on a signification portion of the keys, e.g., a majority of the keys. For example, with three functions per key the already small keys may include up to three indicia (e.g., legends) on them to describe each function. Accordingly, loading of the physical keys with secondary and tertiary functions may make the overall keyboard look complex. As such, QWERTY keyboards on traditional mobile communications devices were often considered to be targeted for business and not consumer use. Additionally, inclusion of extended functions on each key may make it harder to find a desired key function, e.g., the desired key function may be buried in a sea of key functions that are not used as much by the user.

In one or more implementations, functionality of a physical keyboard (e.g., a QWERTY keyboard) is combined with a display device (e.g., a touchscreen) to offload alternate functions for input (i.e., alternative inputs) from the physical keypad onto the display device. For example, a dedicated hardware key may be used to load a library of secondary and tertiary functions for display on the display device. For instance, a key labeled with a punctuation smiley face “;)” may be used to load punctuation marks and/or emoticons. Thus, the physical keyboard may be simplified to include primary functions and secondary functions used most often to make these functions easy to access and use from day to day, thereby making a keyboard having increased acceptability in the consumer space.

Additionally, these techniques may be leveraged to increase flexibility of the mobile communications device to provide special characters (e.g., as secondary and/or tertiary functions) for specific localization. For example, characters may be identified that commonly utilized in a specific geographic location. Rather than reconfigure the physical keyboard, these characters may be output for selection by leveraging touch screen functionality of the mobile communications device. Further discussion of leveraging a display device for input of secondary and tertiary functions that are not present on a physical keyboard may be found in relation to FIGS. 2, 3, and 5.

In an implementation, at least one physical key of a keyboard of a mobile communications device is configured to be selectable to load additional functions for that physical key which may or may not be indicated on the physical key. For example, a user may press and hold a key and have accents associated with that key loaded automatically as an extended set of that physical key. In Spanish, for instance, the tilde “{tilde over ( )}” might be used in conjunction with a letter Ñ in the word SEÑIOR. In order to load the tilde, a user may press and hold the “N” on the keypad to load an extended set of N's with accents on the display device. A user may then select from the extended set, e.g., using a touchscreen or other cursor control device. Thus, clutter on the keyboard of indications of the multiple functions may be reduced yet still make that functionality available to a user. A variety of other examples are also contemplated, further discussion of which may be found in relation to FIGS. 4 and 6.

In the following discussion, a variety of example implementations of a mobile communications device (e.g., a wireless phone) are described. Additionally, a variety of different functionality that may be employed by the mobile communications device is described for each example, which may be implemented in that example as well as in other described examples. Accordingly, example implementations are illustrated of a few of a variety of contemplated implementations. Further, although a mobile communications device having one or more modules that are configured to provide telephonic functionality are described, a variety of other mobile devices are also contemplated, such as personal digital assistants, mobile music players, dedicated messaging devices, portable game devices, and so on.

Example Implementations

FIG. 1 is an illustration of an example implementation 100 of a mobile communications device 102 in accordance with one or more embodiments of devices, features, and systems for mobile communications. The mobile communications device 102 is operable to assume a plurality of configurations, examples of which include a configuration in which the device is “closed” and a configuration illustrated in FIG. 1 in which the device is “open.”

The mobile communications device 102 is further illustrated as including a first housing 104 and a second housing 106 that are connected via a slide 108 such that the first and second housings 104, 106 may move (e.g., slide) in relation to one another. Although sliding is described, it should be readily apparent that a variety of other movement techniques are also contemplated, e.g., a pivot, a hinge and so on.

The first housing 104 includes a display device 110 that may be used to output a variety of data, such as a caller identification (ID), information related to text messages as illustrated, email, multimedia messages, Internet browsing, game play, music, video and so on. In the illustrated implementation, the display device 110 is also configured to function as an input device by incorporating touchscreen functionality, e.g., through capacitive, surface acoustic wave, resistive, optical, strain gauge, dispersive signals, acoustic pulse, and other touchscreen functionality.

The second housing 106 is illustrated as including a keyboard 112 that may be used to provide inputs to the mobile communications device 102. Although the keyboard 112 is illustrated as a QWERTY keyboard, a variety of other examples are also contemplated, such as a keyboard that follows a traditional telephone keypad layout (e.g., a twelve key numeric pad found on basic telephones), keyboards configured for other languages (e.g., Cyrillic) and so on.

In the example shown in FIG. 1, the first and second housings 104, 106 of the mobile communications device 102 are approximately squared. For example, a plane defined by an outer surface of the display device 114 may be parallel to a plane of the first housing 104 that approximates a square, which may be the same as or different from the plane defined by the display device 110. In other words, the width and height of the plane taken from the first housing 104 that is parallel to the other surface of the display device 110 is approximately one-to-one. Likewise, the second housing 106 may be considered square along a plane that is parallel to and/or is the same as an outer surface of the keyboard 112 disposed within the second housing 106.

The mobile communications device 102 may assume a “closed configuration” such that the first housing 104 covers the second housing 106 by sliding the housing together using the slide 108. Consequently, the keyboard 112 disposed on the second housing 106 may be covered and made not available to for interaction by a user of the mobile communications device 102. In an implementation, telephonic functionality is still available when the mobile communications device 102 is in the closed configuration, e.g., to receive a telephone call.

In the “open” configuration as illustrated in the example implementation 100 of FIG. 1, the first housing 104 is moved (e.g., slid) “away” from the second housing 106 using the slide 108. In this example configuration, at least a majority of the keys of the keyboard 112 is exposed such that the exposed keys are available for use to provide inputs. The open configuration results in an extended form factor of the mobile communications device 102 as contrasted with the form factor of the mobile communications device 102 in the closed configuration. In an implementation, the planes of the first and second housings 104, 106 that are used to define the extended form factor are parallel to each other, although other implementations are also contemplated.

The form factor employed by the mobile communications device 102 may be suitable to support a wide variety of features. For example, the keyboard 112 is illustrated as supporting a QWERTY configuration. This form factor may be particularly convenient to a user to utilize the previously described functionality of the mobile communications device 102, such as to compose texts, play games, check email, “surf” the Internet, provide status messages for a social network, and so on.

In the mobile communications device 102 of FIG. 1, a portion of the keys of the keyboard 112 are illustrated as sharing multiple functions. For example, a numeric keypad may be provided within physical keys of the QWERTY layout as illustrated by the physical keys “w”, “e”, “r”, “s”, “d”, “f”, “z”, “x”, “c”, and “.” as sharing numbers “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, and “0”, respectively. The numbers may be accessed by pressing the “ALT” key of the keypad 112. A variety of other examples are also contemplated, an example of which may be found in relation to the following figure.

The mobile communications device 102 is also illustrated as including a communication module 114. The communication module 114 is representative of functionality of the mobile communications device 102 to communicate via a network 116. For example, the communication module 114 may include telephone functionality to make and receive telephone calls. The communication module 114 may also include a variety of other functionality, such as to form short message service (SMS) text messages, multimedia messaging service (MMS) messages, emails, status messages for a social network, and so on. For instance, a user may form a status message for communication via the network 116 to a social network website. The social network website may then publish the status message to “friends” of the user, e.g., for receipt by the friends via a computer, respective mobile communications device, and so on. A variety of other examples are also contemplated, such as blogging, instant messaging, and so on.

The communication module 114 is further illustrated as including a user interface module 118 that is representative of functionality of the mobile communications device 102 to generate, output, and manage a user interface 120 on the display device 110. For example, the user interface 120 is illustrated in FIG. 1 as being configured for SMS text messaging and follows a conversation between a user of the mobile communications device 102 and another user of another mobile communications device via the network 116.

As previously described, conventional loading of the physical keys of a keyboard with secondary and tertiary functions may make the overall keyboard look complex. Additionally, inclusion of indicia of alternative functions on each physical key may make it harder to find a desired key function, e.g., the desired key function may be buried in a sea of key functions. Accordingly, the user interface module 118 may separate functions 122, such as to make a portion of the functions 122 available via physical key inputs 124 and alternate functions available via displayed key inputs 126. In this way, the user interface module 118 may leverage the user interface 120 to provide alternative inputs without cluttering the keyboard 112, further discussion of which may be found in relation to the following figures.

Generally, any of the functions described herein can be implemented using software, firmware, hardware (e.g., fixed logic circuitry), manual processing, or a combination of these implementations. The terms “module,” “functionality,” and “logic” as used herein generally represent software, firmware, hardware or a combination of software and firmware. In the case of a software implementation, the module, functionality, or logic represents instructions (e.g., program code) that perform specified tasks when executed on a computing system formed by one or more computers having one or more processors (e.g., CPU or CPUs). The instructions may be stored in one or more tangible computer readable memory devices. The features of the alternative input techniques described below are platform-independent, meaning that the techniques may be implemented on a variety of commercial computing platforms having a variety of processors.

FIG. 2 illustrates an example implementation 200 in which the mobile communications device 102 of FIG. 1 outputs a user interface configured to leverage functionality of the display device for input of alternate functions. The keyboard 112 includes a plurality of physical keys which include letter keys arranged according to a QWERTY layout as previously described.

A subset of the physical keys of the keyboard 112 includes indicia of both letters and numbers that may be entered using that key. For example, the physical keys “w”, “e”, “r”, “s”, “d”, “f”, “z”, “x”, “c”, and “.” are illustrated as sharing numbers “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, and “0”, respectively. The numbers may input in a variety of ways, such as by pressing an ALT key concurrently with one or more of the keys in the subset. For example, the number “1” may be input by pressing the ALT key and the “w” key that also has indicia of the number “1” marked thereon. Thus, in this example a user may readily provide an input of letters or numbers by interacting directly and exclusively with the keyboard 112.

In the illustrated example, the mobile communications device 102 may be configured to “offload” alternative inputs to the display device 110 for input. For example, a user may select a dedicated physical key 202 (illustrated as including a emoticon formed using punctuation marks) to cause a plurality of portions 204 to be displayed in the user interface 120 to provide alternative inputs. The alternative inputs in the illustrated example include non-alphanumeric characters such as punctuation marks and emoticons. Punctuation marks are symbols other than letters or number used in written language (e.g., “;”). Emoticons represent facial expressions, such as through the use of punctuation marks, e.g., “:)”, punctuation marks and letters, e.g., “:p”, without punctuation marks, e.g., “

”, and so on.

The portions 204 are illustrated as buttons in this example that may be selected using touchscreen functionality of the display device. For instance, the portions 204 in FIG. 2 include punctuation keys that may be selected to cause a respective input by pressing a finger against the display device 110, using a stylus, and so on. Although touchscreen functionality has been described, a variety of other functionality may also be employed to select functions displayed on the display device 110, such as a cursor control device.

In the illustrated example, the user interface module 118 leverages the display device 110 to “offload” alternative inputs that include punctuation marks via respective punctuation keys, example of which include “@” “#,” “$,” “&,” “<,” “>,” “/,” “?,” and “!.” The user interface 120 also includes a key that as displayed includes an emoticon “

.” In one example, the display of the key in the user interface 120 may be selected to cause output of the emoticon directly, e.g., by pressing the display device to use touchscreen functionality. In another example, the key may be selected to access a sub-menu having a plurality of emoticons, further discussion of which may be found in relation to the following figure.

FIG. 3 illustrates an example implementation 300 in which a user interface is configured to provide alternative inputs of a plurality of emoticons, the user interface being output in response to interaction with the user interface 120 of FIG. 2. The user interface 120 in this example includes a plurality of portions, each having a respective emoticon that is selectable to cause the respective emoticon to be input. For example, the display of the button 304 having the emoticon “

” is illustrated as providing an input of “

”306 in a SMS text message.

Although the user interface 120 having portions 304 that are selectable to input emoticons was described as a sub-menu that is accessible via the punctuation menu of FIG. 2, a wide variety of other examples are also contemplated. For instance, the physical key 202 having the emoticon may be selected to cause output of the emoticon library directly. In this instance, another physical key may be dedicated to punctuation marks such that selection of this other physical key may cause the illustrated punctuation library of FIG. 2 to be output directly.

Thus, as described in FIGS. 2-3, functionality of physical keys of a keyboard 112 (e.g., a QWERTY keyboard) may be combined with the display device 110 (e.g., a touchscreen) to offload selected secondary and tertiary functions from the keyboard 112 onto the display device 110. Thus, the physical keyboard 112 may be simplified to include primary functions and secondary functions that are used most often to make these functions easy to access and use from day to day. Although a few examples of offloaded functions are described, it should be readily apparent that a variety of different functions may be offloaded without departing from the spirit and scope thereof, further discussion of which may be found in relation to the following figure.

FIG. 4 illustrates an example implementation 400 in which alternative inputs are displayed on a display device responsive to selection of a physical key of the mobile communications device 102 of FIG. 1 that relate to a primary function of the physical key. For example, a physical key 402 of the keyboard 112 includes indicia indicating a letter “a”. Therefore, the primary function of the physical key 402 is to enter the letter “a” when selected by a user without being selected in combination with another physical key, e.g., the ALT key.

In an implementation, the user interface module 118 may be configured such that alternative inputs are displayed that relate to a particular physical key if the physical key is selected for a specified amount of time. For example, the user may “hold down” the physical key 402 for two seconds, which may cause the user interface module 118 to display alternative inputs 404 that relate to the primary function of the physical key 402 in the user interface 120. In the illustrated instance, the relationship between the primary function and the alternative inputs is that the alternative inputs include a letter that is the primary function, which is shown through different combinations of the letter “a” with symbols that represent accents to be applied to the letter “a”.

In another example, a user may press and hold a key and have accents associated with that key loaded automatically as an extended set of that physical key. In Spanish, for instance, the tilde “{tilde over ( )}” might be used in conjunction with a letter Ñ in the word “SEÑIOR.” In order to load the tilde, a user may press and hold the “N” on the keypad to load an extended set of N's with accents on the display device 110. A user may then select from the extended set, e.g., using a touchscreen or other cursor control device. Thus, clutter on the keyboard 112 of indications of the multiple functions may be reduced yet still make that functionality available to a user. A variety of other examples are also contemplated, further discussion of which may be found in relation to FIG. 6.

Example Procedures

The following discussion describes alternative input techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, or software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to the environment 100 of FIG. 1 and the implementations 200, 300, 400 of FIGS. 2-4, respectively.

FIG. 5 depicts a procedure 500 in an example implementation in which a user interface is output to display alternative inputs. An input is received that is caused by selecting a particular one of a plurality of physical keys of a mobile communications device (block 502).

Responsive to the receiving, a user interface is output on a display device of the mobile communication device having touchscreen functionality (block 504). The user interface includes a plurality of punctuation keys, each being selectable via the touchscreen functionality to cause input of a respective one of a plurality of punctuation marks. At least one key is displayed in the user interface and is selectable via the touchscreen functionality to cause a plurality of emoticon keys to be output in the user interface. Each of the emoticon keys are selectable to cause input of a respective one of a plurality of emoticons. As previously described emoticons may be configured to convey emotions, such as by mimicking facial expressions.

FIG. 6 depicts a procedure 600 in an example implementation in which alternative inputs are output in a user interface that correspond to a letter of a physical letter key. A determination is made that a physical letter key of a keyboard of a mobile communications device has been selected (block 602). For example, the physical key 402 “a” of FIG. 4 may be configured to provide a primary input of a letter “a” and therefore may be referenced as a physical letter key.

If the physical letter key has not been selected for a specified amount of time a letter is input that corresponds to the physical letter key (block 604), such as a letter “a” for the physical key 402 in the previous example.

If the physical letter key has not been selected for a specified amount of time, an alternative input is displayed that includes the letter on the mobile communications device, the display of the alternative input being selectable to input the alternative input (block 606), such as to include one or more accents with the letter in the user interface 120. A variety of other examples are also contemplated.
